Use the relative humidity calculator to explore the relationship between relative humidity, air temperature, and dew point.

Free relative humidity calculator. Find RH, dew point, or temperature using the Magnus formula. Includes comfort levels, ideal indoor ranges (30-50%), and step-by-step examples.

Calculate Temperature, Dewpoint, or Relative Humidity 1) Choose a temperature scale. 2) Enter values in 2 of the 3 boxes. 3) Press "Calculate" to find the missing value.

The Relative Humidity Calculator determines relative humidity (%) based on temperature and dew point using the Magnus-Tetens formula. The calculator allows input in Celsius (°C), Fahrenheit (°F), or …

Dew point to relative humidity conversion calculator to find the amount of moisture (water vapor) in the air compared to the amount of moisture that air can hold at the temperature.

We now have a dry bulb and a wet bulb temperature which we can use to calculate relative humidity. The easiest way to do this is entering the dry and wet bulb temperatures into the calculator above …

This relative humidity calculator can estimate the relative humidity, air temperature or dew point temp by taking account of the rest of the two variables from the formula.
